Problems solved by technology
[0002] At present, with the continuous development of power electronics technology, the loss of power components is increasing, and the traditional air-cooled heat dissipation technology can no longer meet the needs of use. Therefore, water cooling technology is constantly being promoted and applied. Water cooling system is currently The most widely used water cooling equipment in the power industry mainly includes three parts: the water cooling system body, the external circulation cooling device and the operation information collection equipment
[0003] As a key equipment, the water cooling system will have a very important impact on the power equipment it serves whether its operation is stable or not. Considering that the environment in which the application is located is a high-voltage electric field, the current water cooling system has a great influence on the water quality parameters of the treated cooling water. There are strict monitoring to avoid problems such as partial discharge and other electrical tests that cannot pass after the cooling water enters the electric field, and there is little involvement in the monitoring of the operation status of the external circulation cooling device that affects the secondary heat exchange capacity
[0004] After long-term use of external circulation cooling equipment, the working capacity will be reduced. Therefore, it is necessary to pay attention to inspection and maintenance from time to time, otherwise it will pose a great threat to the operation of the overall equipment.
